Embrace Change!

If the best answer you can honestly come up with as to why you do something a certain way is because it's the way you have always did it, it's time to reevaluate your reasoning!  Training is no exception.  In order to make continual gains in fitness, we have to be open to change.  The body responds in a positive manner to change.  So if you are doing the same workout you did 30 days ago, change some things up.  Increase the number of sets, increase weight, focus on the negative phase during weight training exercises, increase duration, switch up the order in which you do your workout, reverse your cycling route, do something that's different and I promise you'll see some results and break through those training plateaus that are common.  Not to mention you might actually find that you love working out again :)
